answer:
x = 8
one thing you should know for the sides of isosceles triangles is:
x , x , x
so, now plug in what we have.
since we have 8
, x would be 8.
Answer:
216 degrees is the answer.
Step-by-step explanation:
The vertical height of the cone = 8 cm
The radius of the cone = 6 cm
The perimeter or circumference of the base of the cone is given by:
P = 
= 
Now the slanted height is calculated using Pythagoras theorem:
H = 
= 
= 10
Let 'θ' is the sector angle that we have to find.
Arc length of the sector is equal to the perimeter.
Arc length =
θ
θ
θ=
(radian)
we know that 1 pi radian = 180 degrees.
So, 1.2 pi radian =
degrees
Answer:
67
Step-by-step explanation:
Use the average formula: average = sum of elements / number of elements
Let x represent the score of their last game, and plug in the average, other scores, and number of elements into the equation:
56 = (48 + 57 + 52 + x) / 4
Simplify:
56 = (157 + x) / 4
Solve for x, by first multiplying each side by 4:
224 = 157 + x
Subtract 157 from both sides:
67 = x
So, the score of their last game was 67.
The rate of change would be $5 per hour with the graph starting at $8
